Planning for the procedure is necessary before you even make the final decision to have it done. Once that step is completed, you will be ready to start the preparations for your surgery. Before you are approved for a hair transplant procedure, the doctor will have to sign off on you. You must be deemed appropriate for the surgery. A doctor who is skilled in doing hair transplant procedures on young people will do some investigation before tackling such a project. He will ask to see members of the family to assess their hair loss and how the young person might inherit hair loss traits from the family. If family members cannot be present, the doctor might ask for photos. If the patient does not have straight hair, her curly hair must be inserted by rotating it so that it lies even with the curve of the brow that is being made. One drawback to eyebrow hair transplant surgery is that eyebrow hair, which usually does not grow, will grow and need to be cut because it is actually scalp hair. Certain doctors have been aware of follicular units for a long time now, but the knowledge only recently made its way into hair transplant methods. Now these ideas are being used in hair restoration every day. To understand how follicular units have affected hair transplant surgery practices, it is necessary to first understand what a follicular unit is. Up to 800 grafts can be done in one sitting now. There is still room for improvement, though, as the results still do not look completely natural as they should. A new method of hair transplant that is being used by some doctors today is follicle-unit micro-grafting. In this procedure, grafts are made up of 1-4 hairs and are placed over the balding area. Whether the hair is curly or straight determines if the hair will lie flat or stand up, creating more fullness. Another important factor for hair transplant is the color of the hair in contrast to the color of the skin. For a light-skinned man with light-colored hair, or a dark-skinned man with dark colored hair, it takes a certain amount of hair to cover the baldness.
